Advanced Loop-Type Cross Belt SorterEngineered for Precision and Warehouse Efficiency

The Realkey Cross Belt Sorter is a cutting-edge logistics solution, expertly designed to streamline the handling and sorting of parcels, cartons, and packaged goods. This fully integrated system combines track-based mechanics, intelligent carts, perpendicular conveyor belts, and smart communication protocols to deliver high-speed, high-accuracy item distribution. The belt mechanism on each cart operates at targeted locations to ensure each item is placed in the correct chute with pinpoint accuracy.
Available in looped (circular) and linear track designs, this equipment offers scalable throughput. The circular model achieves speeds up to 2 m/s, processing around 22,000 items per hour, while the linear option reaches 1.5 m/s and sorts approximately 8,000 units per hour. These systems are indispensable in sectors such as e-commerce, courier services, fashion logistics, pharmaceuticals, airports, and consumer goods.
